[Current]Welding consumables — Covered electrodes for manual metal arc welding of non-alloy and fine grain steels — Classification
AS/NZS 4855:2022 identically adopts ISO 2560:2020, which specifies requirements for the classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of non-alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.
